Antirrhinum plant named ‘Sulte Pur’

ABSTRACT

A new and distinct cultivar of  Antirrhinum  plant named ‘Sulte Pur’, characterized by its outwardly spreading, decumbent and mounded plant habit; freely branching habit; freely flowering habit; and numerous flowers that are purple in color.

Botanical classification/cultivar designation: Antirrhinum×hybrida cultivar Sulte Pur.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Antirrhinum plant, commercially known as a trailing Snapdragon, botanically known as Antirrhinum hybrida, and hereinafter referred to by the cultivar name Sulte Pur.

The new Antirrhinum is a product of a planned breeding program conducted by the Inventor in Gilroy, Calif. The objective of the breeding program is to create new early and freely flowering Antirrhinums with trailing and mounded plant habit and attractive leaf and flower coloration.

The new Antirrhinum originated from a cross-pollination made by the Inventor in September, 2000 of a proprietary selection of Antirrhinum hybrida identified as code number 167A, not patented, as the female, or seed parent, with a proprietary selection of Antirrhinum hybrida identified as code number 7, not patented, as the male, or pollen parent. The new Antirrhinum was selected as a single plant from the resulting progeny of the cross-pollination in a controlled environment in Gilroy, Calif. in May, 2001.

Asexual reproduction of the new cultivar by terminal vegetative cuttings since May, 2001, in Gilroy, Calif. has shown that the unique features of this new Antirrhinum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sulte Pur have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sulte Pur’. These characteristics in combination distinguish ‘Sulte Pur’ as a new and distinct cultivar:

-   -   1. Outwardly spreading, decumbent and mounded plant habit.     -   2. Freely branching habit.     -   3. Freely flowering habit.     -   4. Numerous flowers that are purple in color.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Antirrhinum differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Antirrhinum were more freely branching than         plants of the female parent selection.     -   2. Plants of the new Antirrhinum had shorter internodes than         plants of the female parent selection.     -   3. Plants of the new Antirrhinum and the female parent selection         differed in flower color as plants of the female parent         selection had red-colored flowers.

In side-by-side comparisons in Gilroy, Calif., plants of the new Antirrhinum differed from plants of the male parent selection in the following characteristics:

-   -   1. Leaves of plants of the new Antirrhinum were darker green in         color than leaves of plants of the male parent selection.     -   2. Plants of the new Antirrhinum flowered more uniformly across         the plant than plants of the male parent selection.     -   3. Plants of the new Antirrhinum and the male parent selection         differed in flower color as plants of the male parent selection         had pink-colored flowers.

Plants of the new Antirrhinum can be compared to plants of the cultivar Luminaire Deep Purple, not patented. In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Antirrhinum differed from plants of the cultivar Luminaire Deep Purple in the following characteristics:

-   -   1. Leaves of plants of the new Antirrhinum were more oblong than         and not as round as leaves of plants of the cultivar Luminaire         Deep Purple.     -   2. Plants of the new Antirrhinum had smaller flowers than plants         of the cultivar Luminaire Deep Purple.     -   3. Flower color of plants of the new Antirrhinum was more         saturated than flower color of plants of the cultivar Luminaire         Deep Purple.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Sulte Pur have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice in a polyethylene-covered greenhouse during the summer with day temperatures ranging from 24 to 29° C., night temperatures ranging from 13 to 18° C. and light levels about 2,000 foot-candles. Plants used for the photographs and description were about 12 weeks from planting rooted cuttings. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
